The former Kanawinka Geopark is situated along a structurally controlling geological fault of the same name that extends from the Naracoorte Caves in South Australia into Western Victoria, before disappearing offshore at Portland. The South Australian portion of the Geopark lies in the Limestone Coast of the state, and adjoins the World Heritage area of Naracoorte Caves. The Victorian part lies in the Western Districts region of that state. Both areas are famous for their cheese, wine, forestry and rural industries.
